Just found a signal on the National Archives DEFE 3 site stating that the Italian vessel "Carbonello" was to load at Olbia with ammo and sail to Italy on 5.8.43, on checking in J.Rohwer Allied Submarine Attacks he has "Carbonello" as being mined and beached on the 23.3.43 and later used as a blockship (where)? are they the same vessel after being beached was she refloated and used as a towed barge and then sunk as a blockship. peter.r
